Mara fixed visual artifacts for a living. She was one of the few who could read rendering logs like poetry. When the broadcast hit, her inbox filled with panic: flickering faces, floating geometry, forbidden color bands that made people sick. She traced the anomaly to a shader instance—ID errgfxd3dshader1—running on a deprecated node in the city's subterranean server farm.
